Jung, Carl Gustav (1875–1961)

Carl Jung was a Swiss psychologist and psychiatrist who founded analytic psychology. Jung
studied psychiatry at Basel University, his postgraduate studies being in
parapsychology. After working with Bleuler and Janet, he met Sigmund Freud
(1907), whom he followed for some years. But he disagreed with, particularly,
Freud's belief in the purely sexual nature of the libido, and in 1913 he
broke away completely.

In Psychological Types (1921) Jung expounded his views on introversion
and extroversion. Later he investigated anthropology and the occult to form
the idea of archetypes, the universal symbols present in the collective
unconscious.

Jung believed that a direct encounter with intellectually superior beings
would be disastrous for our race:

[Th]e reigns would be torn from our hands and
we would, as a tearful old medicine man once said to me, find ourselves
'without dreams,' that is, we would find our intellectual and spiritual
aspirations so outmoded as to leave us completely paralyzed.
